‘Mr Curtis said he hoped to take a primary school teacher and a secondary school science head teacher with him on his trip, which could be in May.’

‘About 90 percent of students who finish elementary school continue their education at the secondary level.’

‘I teach them for eight years before they go to boarding school to complete their secondary education.’

‘As the Secretary of State for Education embarks on secondary curriculum revision, can we hope he will seize a tide?’

‘Such a system is needed to make post secondary education more accessible.’

‘All but two students had received secondary school education in the United Kingdom.’

‘Recommended course series for early childhood educators, elementary educators, and secondary educators have been designed.’

‘Very few teachers, especially in secondary schools, were funded to develop new curricula for themselves using computers.’

1.2Having a reversible chemical reaction and therefore able to store energy.

‘the lead-acid accumulator used in cars consists of secondary cells’

‘ATP is the power molecule used all over organisms and their cells to power the secondary reactions that keep us alive.’

1.3Relating to or denoting the output side of a device using electromagnetic induction, especially in a transformer.

‘the primary and secondary coils of the transformer’

‘The reverse polarity creates a peak current about twice as high as the six amps of coil current on the primary side, and a higher peak-to-peak current on the secondary side.’

‘It's broadly the same way a power transformer works, with a primary coil generating a current in a secondary coil, the difference between the number of loops in each coil governing the change to the voltage.’

‘The burst in current causes a change in voltage in the secondary coil, which in turn causes a change in voltage in the feedback coil.’

‘The alternating flux in the core in turn induces an alternating current in each of the secondary coils.’

‘Apply the ac voltage to the primary winding and expect output voltage at the secondary side.’

‘We learn that there was a time when Cephalopoda were the highest types of animal life; and that during the secondary period they were anatomically raised far above any forms of the reptile class now living in the world.’

3Chemistry (of an organic compound) having its functional group located on a carbon atom which is bonded to two other carbon atoms.

‘In this example, the first molecule is a primary alcohol and the second is a secondary alcohol.’
